Water-vaporizer.



Umm STATES 'LAFAYETTE n. SMITH, or SEATTLE, WASHTNGTO, Assieivon or own-Hann To I HowAnD T. GRAHAM, oEKINe COUNTY, WASHINGTON:

To all/whom it may concern.'

Be it known that I, LAFAYETTE a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Water-Vaporizers, of which the following is a full, true, and exact specication.

My invention relates to improvements in water vaporizers and more particularly to devices of this general character which are used to mix air and water for injection into gas engine manifolds, and has for its principal object to provide an improved and novel device of the class described, which is attachable to the manifold of a gas engine; to provide improved construction for separating the water into minute particles and mixing it with the air; to provide a device which is automatically operated by the suction of the engine. It is a well-known fact that the introduction of air containing a small amount of moisture into the charge of a gas engine has the effect of saving gas and keeping the cylinders clean. My device is designed to mix the water and air in proper proportion previous to its introduction into the manifold.

Other obi ects will annear as my invention is more fully explained in the following specification, illustrated in the accompanving drawings and pointed out in the appended claims.

In the drawings, Figure 1 is a central cross section of my device shown attached to the fragmentary gas engine manifold. Fig. 2 is an end elevation of same. Fig. 3 is an enlarged fragmentary section of a valve seat portion of my device.

Referring more particularly to the drawings, numeral 1 indicates a tank receptacle having a cover 2 which fits tightly upon its top. Integral with the base of the tank is a valve bodv 8 having a tapered valve seat 4 which is located beneath the tank 1. One end of the valve body 3 is provided with a perforated screw cap 5 while the other end is threaded for a pipe connection 6 which is screwed into a manifold 7 A tapered valve 8 normally closes tightly against the seat 4 and is provided with a stem 9 which passes through cap 5. A spring 10 is wound about the stem 9 and has its lower end bearing against the outer face of can 5 while its 11pper end bears against a washer 11 which is E. SMITH,

Specification of Letters Patent.' l Pgtnted Dec,` 18, 1917 Appncation mea July 29,1916.- seriai 110; 112,096. Y f i adjustably held in place byfmeans of nuts 12. It will be understood that the valve 8 1s held in a seated position with respect to seat 4 by means of the tension in the spring l0 but that spring 10 is not of sufficient strength to prevent the suction of the gas engine from lifting the valve from its seat. A water inlet port 13 is cut in the bottom of tank 1 and communicates witha circular passage 14 and which passes entirely around the outside of valve seat 4. Small inlets 15 are drilled through from the inner side of valve seat 4 to connect with circular passage 14. Fine grooves 16 are cut in the surface of seat 4 between the outlets 15. A needle valve 17 is provided to adjustably close and open the port 13.

The operation of my device is as follows: The suction of the gas engine raises the valve 8 from its seat 4 and allows the air to rush in around the periphery of the said valve. At the same time water is allowed to flow in to the passage 14 and out of the small outlets l5. After the water ows out of the outlets 15 it follows the little grooves 16 and as the air rushes past the said grooves and outlets the water is vaporized and carried along by the air. It is thus seen that the proper admixture of air and water for any given condition may be obtained by the adjustment of spring 10 and the valve 17.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described. Having described my invention what I claim as new and desire to protect by Letters Patent, is-

1. In a device of the class described, the combination of a tapered valve, a valve body having a tapered valve seat, a continuous passage which surrounds said seat in said valve body, a continuous groove formed of arches cut in the face of said valve seat, and a series of very ne perforations connecting the said passage with the points of connections of the said groove arches, one with another.

2. In a device of the class described, the combination of a tank having a cylindrical body portion at its lower end formed with a tapered valve seat having? a continuous groove on its inner surface, a continuous, paetank, an inclined adjustable valve mounted 10 Sage. ormed in the cylindrical body portion the side of the tank n alneinent with. the and surrounding said Valve seat, a plurality inclined portV to regulate the latter, a Japered of outlet openings formed i'n the cylindrical' valve normally fitting in the valve Seat, a body portion and communicating with the stem- @Xtending from the Valve, and a spring passage and leading to the continuous groove on the stem to normally bold the valve in 15 on the serielle. of the. tapered Valve Seat, ants. Seat.,

inclined port formed i'n the body portion and leading from the continuous passage to the LAFAYETTE E. SMITH.
